What amp to tame Eggleston Works Esotar Tweeters?

My speakers are Eggleston Works Andra ll and Andra center. My rears and sides are also EW. My processor and amp are Lexicon MC12B and LX-7 (made by Crown). 99% theater use in a 7.1 system. Left speaker 25', center 17' and right is 10'. My room is fully treated.

The problem is the Eggleston Works speaker Esotar tweeter are very revealing and I am sure the Lexicon amp is not helping any either. My ears are very sensitive to high frequency sound such as edgy treble.

I may change out the LX-7 amp for an Ayre 7xe, Mcintosh or a Sanders ESL, Classe or Rogue Audio Medusa amp... to also help smooth/warm up the sound a bit. Feel free to comment on which amp I should go with or others not listed.

My speaker wire is: xlr JPS Aluminata and Super Conductor 3 with Aluminata power cords. My line conditioner is a Furman It-Ref 20 i.

Thanks.
